move the ObjectCache from the IRCompileLayer to SimpleCompiler.
This is the first in a series of patches aimed at cleaning up and improving the
robustness and performance of the ORC APIs.

clang-format (https://reviews.llvm.org/D33932) to keep primary headers
at the top and handle new utility headers like 'gmock' consistently with
other utility headers.
No other change was made. I did no manual edits, all of this is
clang-format.
This should allow other changes to have more clear and focused diffs,
and is especially motivated by moving some headers into more focused
libraries.

frames.
RuntimeDyld was previously responsible for tracking allocated EH frames, but it
makes more sense to have the RuntimeDyld::MemoryManager track them (since the
frames are allocated through the memory manager, and written to memory owned by
the memory manager). This patch moves the frame tracking into
RTDyldMemoryManager, and changes the deregisterFrames method on
RuntimeDyld::MemoryManager from:
void deregisterEHFrames(uint8_t *Addr, uint64_t LoadAddr, size_t Size);
to:
void deregisterEHFrames();
Separating this responsibility will allow ORC to continue to throw the
RuntimeDyld instances away post-link (saving a few dozen bytes per lazy
function) while properly deregistering frames when modules are unloaded.
This patch also updates ORC to call deregisterEHFrames when modules are
unloaded. This fixes a bug where an exception that tears down the JIT can then
unwind through dangling EH frames that have been deallocated but not
deregistered, resulting in UB.
For people using SectionMemoryManager this should be pretty much a no-op. For
people with custom allocators that override registerEHFrames/deregisterEHFrames,
you will now be responsible for tracking allocated EH frames.

The current ObjectLinkingLayer (now RTDyldObjectLinkingLayer) links objects
in-process using MCJIT's RuntimeDyld class. In the near future I hope to add new
object linking layers (e.g. a remote linking layer that links objects in the JIT
target process, rather than the client), so I'm renaming this class to be more
descriptive.

This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class
that is capable of lazy materialization (i.e. the symbol definition needn't be
emitted until the address is requested). This can be used to support common
and weak symbols in the JIT (though this is not implemented in this patch).
For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver.
For space efficiency a new class, JITEvaluatedSymbol, is introduced that
behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an
address and symbol flags. Instances of JITEvaluatedSymbol can be used in
symbol-tables to avoid paying the space cost of the materializer.

Doing "I++" inside of an EXPECT_* triggers
warning: expression with side effects has no effect in an unevaluated context
because EXPECT_* partially expands to
EqHelper<(sizeof(::testing::internal::IsNullLiteralHelper(MockObjects[I++] + 1)) == 1)>
which is an unevaluated context.

Summary:
Update ObjectTransformLayer::addObjectSet to take the object set by
value rather than reference and pass it to the base layer with move
semantics rather than copy, to match r258185's changes to
ObjectLinkingLayer.
Update the unit test to verify that ObjectTransformLayer's signature stays
in sync with ObjectLinkingLayer's.

Summary:
This is a utility for clients that want to insert a layer that modifies
each ObjectFile and then passes it along to the next layer.
